Challenging HVAC careers abound in manufacturing, contracting, building operations and in the engineering of commercial, institutional and industrial building systems.

Wireless sensor network for HVAC control [Master’s thesis].

These industries look for trained HVAC engineering technicians for a variety of HVAC positions, including applications engineer, project engineer, systems control, estimator, HVAC technician, systems representative, control systems trainer and in-plant HVAC engineer. There also are many opportunities to be found with architectural and engineering firms.

Delivering clean air and providing thermal comfort for building occupants are the goals of Heating, Ventilation and Air Conditioning (HVAC) systems. Ventilation process includes the exchange of air to the outside and circulation of the indoor air. In both cases, the air that circulates through HVAC ducts contains fungi and moisture. Combination of fungi, moisture and organic materials creates a suitable environment for mold growth inside the ducts. Studies prove that duct-cleaning process can reduce the amount of pollutants present in the ducts; thus, it has a positive impact on psychological and physical health of the society. The difficulties of the duct cleaning process and unreachable duct networks inspired duct-cleaning firms to employ simple robotic platforms for this task. As my MS thesis in Mechatronics, I have designed a novel duct-cleaning robot (DCR) which addresses challenges and limitations of the current commercially available DCR platforms. This project also includes two detailed and exhaustive surveys on available DCR platforms and climbing robots to address the following points: I) gather and categorize the requirements and limitations of the current available DCR solutions, duct-cleaning processes and techniques implemented by different firms; II) to categorize available climbing robot platforms from agility, versatility and performance and points of view. Additionally, through an exhaustive study of duct conditions and possible maneuvers by robots, we have proposed and proved the minimum requirements of a robotic platform that can pass through any possible situation in air duct channels. Consequently, the following design criteria are assumed for the conceptual design of the robot. I) The robot needs to be able to move on both vertical and horizontal planes with rectangular or circular cross sections. II) It requires performing surface-to-surface transitions between duct planes with the minimum possible number of active degrees of freedom as proofed before. III) Efficient locomotion systems are desired to minimize the power consumption of the system. IV) The robot is going to be available on industrial market, thus fabrication and maintenance costs must be minimized.

Considering the required design criteria, a conceptual design of a climbing DCR (named as Duct-Sweeper) is proposed as a bipedal mechanism that is equipped with two wheeled locomotion and deployable adhesion systems. Using the proposed structure, Duct-Sweeper can ascend and descend vertical paths by pushing the wheels against the duct walls via its waist mechanism to provide enough friction to carry the weight of the robot and use its bipedal locomotion as needed. The waist of the robot is a hybrid (serial-parallel) mechanism that satisfies the workspace requirements for all the required maneuvers of the robot. Additionally, the structure of the robot is formulated as an optimization problem to find the optimal robot dimensions for various duct systems in different buildings. Although the introduced platform is intended to serve as HVAC DCR, Duct-Sweeper is adoptable to many other applications by introducing very small changes to the adhesion and wheeled locomotion systems. Finally, all possible primitive actions and combined maneuvers of the robot are tabulated in the planning section to form the initial steps towards autonomous planning of the robot. The conceptual and detailed design of different parts of the robot are illustrated in the following figures.
